IMPROVEMENT "IN MOSQUITONET FRAMES.

Specification forming part of Letters Patent No. 133,279, dated November 19, 1872.

To all whom it may concern.-

Be it known that I, WILLARD .M. WHITE, of Canton, in the county ofHartford and State of Connecticut, have invented certain new and useful Improvementsin FoldingMosquito- Net Frames, of which the following is a specification,referencebeing had to the accompanying drawing, in which- Figure l is a side elevation of the device,

. extended and attached to a bedstead. Fig. 2

is a plan or top view of that part of the device which may be termed the spreader. Fig. 3 is an enlarged detached top view of that part of the device which may be termed the spreaderjoint, extended. Fig. 4 is a side view of the parts shown in Fig. 3. Fig. 5 is a detached enlarged side view of that part of the device which may be termed the clamp. Fig. 6 is a side view of that part of the device which maybe termed the F extending-rod, folded up; and Fig. 7 is a view of the spreader folded The device is a frame for supporting a mosquito net or bar attached to a bedstead or its equivalent.

The letters a b c d indicate the four joints of an extending-rod, which will fold together, as shown in Fig. 6, the joints being properly hinged together for that purpose, or which may be unfolded or extended, as shown in Fig. 1. A pawl, b, is so hinged to the joint I) that it will lie in a slot in the side of the joint when the extending-rod is to be folded up, and which is used to sustain the horizontal part of the extending-rod when the rod is unfolded or extended. There are different notches in the under side of the joint 0, into which the end of the pawl fits, so that the horizontal part may be elevated, within suitable limits, as desired. 'A clamp fits upon the joint a, having a socket or sockets, 6 e which slide upon the joint. Attached to this socket, by a pivot or hinge joint, is the clamping-hand f, pulled toward the joint a by the spring f so that the joint on and this clamping-hand will embrace the head 9 of the bed, or any other proper support, tightly enough to support the otherparts of the device. 0n the end of the joint d is a pin, d, extending upward, on which 4 pin sits the spreader, this pin entering the center of the spreader-joint. This spreaderjoint has acentral body, h, to the two opposite into which are rigidly fixed the spreaderarms 70 k, and to which are hinged the arms on m m m, which latter arms are shown extended in Figs. 2 and 3, but which can be folded flatly against the arms 70 70 when the device is to be folded up, and when these arms are thus folded up the whole can be folded up, as shown in Fig. 7. When the spreader is extended the pawl-points t" t" prevent the spreader-arms from fallin g below a horizontal. To the ends of the spreader-arms may be attached, either temporarily or permanently, a cord, 0. If the attachment is to be temporary, I prefer to use an elastic cord and to have the ends of the arms appropriately grooved to receive the cord and hold it. Instead of attaching the extending rod to the head-board by a spring clamp, it may be done by means of a screwclamp. The pin d has a little play, so that the spreader may be kept horizontal however much the extending-rod is elevated. It is preferable that the end of the hand f be equipped with rubber or other soft cushions, f so as not to mar the bed. When the rod is folded up, as shown in Fig. 6, the pin d enters a hole made for it in the joint c, as shown in dotted lines.

The netting is, of course, suspended upon the spreader, and falls from thence upon and over the bed.

From this description it is seen that the whole is composed of only three pieces-the spreader, extending-rod, and clamp-and that the whole can be folded up into a very small compass. The socket e is attached to the piece 6 the upper end of which is pivoted within the socket 0, thus forming, as a whole, a new and peculiar socket.

I claim as my invention- 1. The combination of the clamp, the rod a b c d, and the spreader, constructed and arran ged to operate, substantially as described, for the purpose set forth.

2. The jointed extending-rod provided with the pawl 12, the whole constructed and de signed for use, substantially as described, for the purpose set forth. 1

3. The clamp composed of the two sockets the one hinged to the other and provided with, the hand f, equipped or unequipped with the sides of which are pivoted the pawl-sockets M, 5. The spreader-joint, as specified in the last cushion f the whole constructed and designed clause, combined with the arms is k, and the to operate substantially as described, for the arms on hinged thereto, substantially as depurpose set forth. seribed,and for the purpose set forth.

4. The spreader-joint composed of the cen- WILLARD M. WHITE. tral body h and the pawl-sockets & hinged Y thereto, and provided with the pawl-points i, Witnesses:
